Is the Hi-Z preamp suitable for use on 630m (475kHz) with the 25-ft vertical? I understand the array spacing and phasing will be different, but I can play with that in EZNEC.

It is the different arrays that I make that may or may not be broadband. I suggest you talk to W7IUV as he has done quite a bit of work using my Hi-Z amps on VLF. Might be very enlightening. I would have to do some testing to verify my arrays would hold amplitude and phase tracking at 630 meters.
